We know different number systems. But how many of us know about theconstants associated about the different number systems. I will givesome examples, example 1: if you divide the sum of any two digit number and itsreverse by the sum of the two digits comprising the number, then theresult is always 11 in decimal system. So irrespective of the 2-digitnumber you choose, the result will always be 11, So 11 is costant ofoperation of the above process. There are a lot of such constants forevery number system. These constants are known as MEMI constants.
